It was a great honor for us to preside over the Hip Biomechanics Symposium held on November 19
1992 in Fukui City Japan. We believe it was the first interdisciplinary conference on
biomechanical approaches to hip disorders this volume contains the presentations made at the
conference. The information found here will be of value not only for orthopedic surgeons but
also for researchers. The advent of biomechanical approaches to hip dis ease has made possible
the understanding of fundamental hip pathologies an understanding which enables us to
institute the appropriate non-surgical or surgical treatment. Indeed efficient surgical
planning is not possible without taking these approaches. This comprehensive volume consists of
six major sections: loading gait analyses THA osteotomies motion analyses and stem designs
for stability. Each of these sections brings together many of the leading researchers in this
field. We hope this volume will be a spur to future understanding of and on fruitful research
on hip disorders. The Editorial Committee wish to express their deep gratitude to the contri
butors and the publisher. Shinichi Imura Noriya Akamatsu Hirohiko Azuma Kazuhiko Sawai Seisuke
